In his eWorld keynote, BEA's chief architect, Adam Bosworth, cited the similar transformation around the GUI, which gave procedural control to users. Now RSS is creating another shift, away from the Web request model to user-controlled aggregation. TiVo-like user metadata can be harvested to offer services in return for access to group and trend data. And as RSS containers become more intelligent about applying authority filtering to feeds, the signal to noise improves. Bosworth showed eWEEK Senior Writer Darryl K. Taft and me an intelligent RSS router, built atop his Alchemy extended browser project, a framework that uses declarative metadata dynamic caching to create a rich conversation between a thin client and the server cloud. Sounds like HailStorm, I told Bosworth, who didn't disagree. But a HailStorm based on a framework BEA will open-source.
